What Is Network Penetration Testing?

Imagine you're a white-hat hacker and have to break into your own company's network. This is essentially a network penetration test. It's similar to a controlled attack in that it identifies and fixes vulnerabilities before real hackers do.

Instead of beginning from scratch and attempting to break in, a network pentest presumes you are already on the network. This allows security professionals to focus on testing the safeguards designed to stop hackers once they've gained access.

To accomplish this, ethical hackers use specialized tools to scan for weaknesses, navigate the network, and move about undetected. That is where this guide comes in. We'll show you some of the greatest pentest-tools scan your network in the industry to help you become a network penetration tester.
